Three uses of the semicolon
Each use needs complete units on both sides, or list items that already have commas inside.
| Use | Example |
|---|---|
| Join two related independent clauses | The shop closed early; the owner was ill. |
| Before a linking adverb that starts the second clause | The rent is high; however, the location is perfect. |
| Separate list items that contain commas | We met Anil, a doctor; Sana, a lawyer; and Joe, a chef. |
The test: a full sentence on each side
When you use a semicolon to join clauses, both parts must be able to stand alone as sentences. If you could replace the semicolon with a full stop, it is correct.
"Although it was cold; we went out" fails, because the first part is a dependent clause. Use a comma there: "Although it was cold, we went out."
Don't use a semicolon with and, but or so; use a comma with those. The semicolon already does the joining.
Semicolon or colon?
A semicolon links two balanced, related ideas. A colon introduces something that explains or lists what came before: "She had one aim: to pass." If the second part is a list or an explanation, use a colon.
Common mistakes
Wrong: Because the road was closed; we took a detour.
Right: Because the road was closed, we took a detour.
The first part is a dependent clause, so it needs a comma, not a semicolon.
Wrong: You will need; a passport, a photo and a form.
Right: You will need a passport, a photo and a form.
A semicolon can't introduce a list. Here no mark is needed at all.
Wrong: Prices rose; and wages fell.
Right: Prices rose, and wages fell.
Use a comma before and. Use a semicolon only without a joining word.
Using this in IELTS and PTE
One or two well-placed semicolons in an IELTS Task 2 or PTE essay can show control, especially with however and therefore. You don't need them; full stops are just as correct. Avoid them in PTE Summarize Written Text, where your answer must be a single sentence and a semicolon can make it read as two.

Frequently asked questions
What is the difference between a semicolon and a full stop?+
Both can separate two independent clauses. A semicolon shows the two ideas are closely linked; a full stop makes a cleaner break.
Does the word after a semicolon take a capital letter?+
No, unless it is a name or another word that always takes a capital: "It was late; we left."
Can I use a semicolon before but?+
Usually no; use a comma. Some writers use one before but in a very long sentence that already contains commas, but in exam writing a comma is safer.
